I tried many times and still recieving the same. But at the same time I tried with anotjer airtel number and I recieved the unique porting code(upc) at that momment itself.
I tried contacting the customer care and they are least bothered about the same and asking me to wait for 1 week.

I saw many customers having the same issue in the internet and they all got their UPC after complaining in the consumer helpline.

My number which I am wishing to port is +91-[protected]
